Application filed. December 18, 1916.

To all whom it may concern: 7

Be it known that I, CHESTER A. PERKINs, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Masons Jointers, of which the following is a specification.

The invention relates to a masons tool adapted primarily for uniformly and handily removing mortar from between courses of bricks and the like to provide grooved or recessed joints, that ismortar joints between layers of bricks in which the mortar is dug or scraped out after the bricks-are laid, so that the joint surface will not be flush with the wall surface, whereby to give the wall as a whole a distinctive and artistic appearance.

The object of the invention is to provide a simple and effective tool adapted for forming mortar joints between courses of bricks, in the use of which the mortar will not only be uniformly cut or scraped out, but which will also expel or remove the severed mortar from between the bricks in the action of making the cut, whereby to provide a neat and clean joint by a single operation of the tool. The tool is to be used before the mortar has thoroughly hardened, and may also be used for smoothing the joint by changing the angle of application, as will farther on appear.

The invention in the preferred form will be described in the following specification, reference being had to the accompanying drawings, in which Figure 1 is an edge view of the tool shown in connection with the representation of a mortar joint.

Fig. 2 is a side view of the tool.

Fig. 3 is an end view of the tool blade.

Referring more particularly to the accompanying drawings, the tool comprises a thin metallic blade 1 of any -suitable material and having the proper rigidity, same being formed with a bent or curved portion 2, forming a bearing surface adapted to engage the surface of the brick wall in the manipulation thereof, and extending on both sides of a mortar joint between two courses of bricks, whereby to regulate the depth to which the cutting-head 3, formed on the outer end of the tool, is to be applied.

The cutting-head 3 is formed by providing the blade with a transverse slit 1, ap-

proximating in length about one-half the I Specification of Letters Patent.

width of the blade, as shown. The blade portion extending from the slit 4 to the end of the blade is thence, to the extent of about one-half the width thereof, bent at rightangles to the blade, as indicated at 5, and the remaining portion bent at right angles to the portion o and in parallelism with the body of the blade, as indicated at 6. The cutting-head 8 is thus formed, of which the inner edges 7 and 8 form the cutting edges, with the blade proper extending beyond either side of the cutting-head, and .a considerable space intervening between the vertical cutting edge 8 and the slitted edge at, to provide an opening through which the cutaway mortar will be directed, as represented by the dotted lines 9 in Fig. 1. The mortar willthus be cut out and expelled from between the brick courses with one operation of the tool. The blade is provided with a suitable handle 10 for manipulating the same.

It will be noted by reference to Fig. 1, that the cutting end of the tool will be disposed at an angle with reference to the wall surface 11, and that the handle 10 will also be disposed at an angle with relation to said wall surface, when the tool is held in operative position. It will thus be obvious that the depth of the cut to be made may be regulated by the distance at which the handle is held spaced from the wall surface, and with the bearing portion' of the blade engaging the wall surface. Also, by reversing the direction of movement, or retracting the tool, the surface 12 thereof will serve to trowel or render smooth the face of the joint roughsued in the act of cutting out the same. It will thus be obvious from the foregoing that, in the manipulation of the tool, the simple act of drawing the tool forward and reversing the same distance, will cut out the joint, expel the mortar severed and smooth the surface of the joint, all without removing or altering the position of the tool.

Having thus described my invention, what is claimed is 1. A jointing tool comprising a blade bent transversely to form an angle and a rounded bearing surface at its point of bend, and an angled cutting head formed at one side of said bearing surface and extending laterally of the blade side, the cutting edge thereof being directed toward the handle end of the blade, whereby the cutting depth of the head may be regulated by rocking the blade on said bearing surface.

2. A jointing tool for brick Walls comprising a blade transversely bent to form an angle and a rounded bearing surface at the 7 point of bend adapted for contact With the Wall surface, and an integrally formed and substantially right-angled cutting head extending laterally of the blade side With its outer portion in substantial parallelism With the blade portion from which it extends, its cutting edge being directed toward the ban dle end of the blade, whereby the depth of copies of this patent maybe obtained for five cents each, by addressing the comanissioneriof Patents,-

the cut of the head between the courses of brick may be regulated by the relative degree of angl'e'maintained between the handle end ofthe tool and the Wall surface.

In testimony whereof I afiiX my signature in presence of tWo Witnesses.
